CCEREBA TRICOLOR (Ridgway). 



OLD PROVIDENCE BANANAaUIT,

 of primaries more extended, white tips to lateral rectrices much 

 larger (about 12.7 long on outermost rectrix) and including both 

 webs, black on lores and beneath eyes much narrower, and white

 with C. hahamensis. 



Adult male. — Above dull black, including the whole of the exposed 

 portion of the tertials and secondaries; a broad and very distinct 

 superciliary stripe of pure white, extending from the nostrils to the

'The single specimen examined from Cayman Brae is obviously different in colora- 

 tion from the five Grand Cayman examples, being much browner (deep hair brown) 

 above, and the yellow of breast and rump inclining more to chrome; but to what 

 extent these differences are due to difference of season (the Cayman Brae specimen 

 was collected in March, those from Grand Cayman in May and July) it is of course 

 impossible to tell without a sufficient series.
